草业发展是维护西藏生态屏障安全的重要内容，也是高原特色畜牧业高质量发展和西藏牧民维持生计的传统优势产业。国家生态安全与粮食安全战略背景下，西藏草业高质量发展受到时空条件的制约。本研究借助城市时空拓展理论，阐明了西藏草业发展时空拓展的必要性和可行性，并依据西藏草业资源的禀赋特征，提出了聚焦生态效益模式、生产效益模式、生态和生产效益兼顾模式，以及实现3种模式的路径，以期为西藏草业未来的发展提供理论指导，也为我国其他地区草业时空拓展提供借鉴。
Spatio-temporal expansion models and pathways for prataculture development in Xizang
The development of prataculture is essential for maintaining ecological integrity in Tibet.Prataculture development is foundational to the high-quality development of the plateau's distinctive livestock industry.It serves as a mainstay for the livelihoods of Tibetan pastoralists.The development of Tibetan prataculture currently faces constraints imposed by national ecological and food security boundaries,specifically spatial and temporal constraints.Utilizing urban spatio-temporal expansion theory,this study analyzes the factors constraining the expansion of Tibetan prataculture,elucidates the necessity and feasibility of spatio-temporal expansion,and proposes models focused on ecological benefits,production benefits,and a balanced approach that considers both.It also provides pathways for implementation of these models.This work offers theoretical guidance for future expansion of prataculture in Tibet,and serves as a reference for the spatial and temporal expansion of prataculture into other regions of China.
